Question : If Rs. 8,500 becomes Rs. 11,050 in 6 years at a certain rate of simple interest, and the rate then becomes 1.8 times higher, what will be the amount after 5 years on the same principal?
Option 1: Rs. 15,625
Option 2: Rs. 14,350
Option 3: Rs. 13,550
Option 4: Rs. 12,325
Correct Answer: Rs. 12,325
Solution : Given: Principal amount = Rs. 8,500 Time = 6 years Simple interest = 11,050 – 8,500 = 2,550 Let the rate be $r$. Now, $\frac{\text{(Principal amount × Time × Rate)}}{100}=\text{Simple interest}=2550$ ⇒ $\frac{8500×6×r}{100}=2550$ ⇒ $r=\frac{2550}{85×6}$ $\therefore r=5$% Now if the rate becomes 1.8 times
Question : The average age of a man and his son is 55 years. The ratio of their ages is 7 : 4, respectively. What will be the ratio of their ages after 6 years?
Option 1: 1 : 2
Option 2: 12 : 7
Option 3: 25 : 17
Option 4: 38 : 23
Correct Answer: 38 : 23
Solution : Let the age of man and son be $7x$ and $4x$ respectively. Average age = $\frac{7x+4x}{2}$ ⇒ $55= \frac{11x}{2}$ ⇒ $x= 10$ Age of man after 6 years = $7x+6$ = 76 Age of son after 6 years = $4x+6$ = 46 Required

Question : A circular running path is 1452 m in circumference. Two men start from the same point and walk in opposite directions at speeds of 7.5 km/h and 9 km/h, respectively. When will they meet for the first time?
Option 1: 5.17 min
Option 2: 5.28 min
Option 3: 5.71 min
Option 4: 5.82 min
Correct Answer: 5.28 min
Solution : Relative speed = (9 + 7.5) = 16.5 km/h Distance = $\frac{1452}{1000}$ = 1.452 km Time = $\frac{\text{Distance}}{\text{Speed}}$ = $\frac{1.452}{16.5}$ hr = $\frac{1.452}{16.5}×60$ min = 5.28 min Hence, the correct answer is 5.28 min.
